Introduction

Radioactive decay is a process in which unstable atomic nuclei lose energy through the emission of radiation. This phenomenon is a fundamental concept in nuclear physics and has numerous applications in fields such as medicine, energy production, and environmental science. In this article, we will delve into the mathematical analysis of the decay of two radioactive compounds, Compound A and Compound B, which are continuously decaying at rates of 12% and 18%, respectively.

Compound A: A 12% Decay Rate

Compound A is continuously decaying at a rate of 12%. This means that every year, 12% of the initial amount of Compound A will decay, leaving 88% of the initial amount remaining. To calculate the amount of Compound A remaining after a certain period of time, we can use the formula for exponential decay:

A(t) = A0 * (1 - r)^t

where A(t) is the amount of Compound A remaining after time t, A0 is the initial amount of Compound A, r is the decay rate (0.12 in this case), and t is the time period.

Let's assume that Tiffany started with 30 units of Compound A. Using the formula above, we can calculate the amount of Compound A remaining after 1 year:

A(1) = 30 * (1 - 0.12)^1 = 30 * 0.88 = 26.4

After 2 years:

A(2) = 30 * (1 - 0.12)^2 = 30 * 0.88^2 = 23.36

As we can see, the amount of Compound A remaining decreases exponentially over time.

Compound B: An 18% Decay Rate

Compound B is continuously decaying at a rate of 18%. Using the same formula for exponential decay, we can calculate the amount of Compound B remaining after a certain period of time:

B(t) = B0 * (1 - r)^t

where B(t) is the amount of Compound B remaining after time t, B0 is the initial amount of Compound B, r is the decay rate (0.18 in this case), and t is the time period.

Assuming that Tiffany started with 30 units of Compound B, we can calculate the amount of Compound B remaining after 1 year:

B(1) = 30 * (1 - 0.18)^1 = 30 * 0.82 = 24.6

After 2 years:

B(2) = 30 * (1 - 0.18)^2 = 30 * 0.82^2 = 20.76

As we can see, the amount of Compound B remaining decreases exponentially over time, but at a faster rate than Compound A.

Comparison of Compound A and Compound B

To compare the decay rates of Compound A and Compound B, we can calculate the ratio of the amount of Compound B remaining to the amount of Compound A remaining after a certain period of time:

Ratio = B(t) / A(t)

Using the values calculated above, we can calculate the ratio after 1 year:

Ratio = 24.6 / 26.4 = 0.93

After 2 years:

Ratio = 20.76 / 23.36 = 0.89

As we can see, the ratio of the amount of Compound B remaining to the amount of Compound A remaining decreases over time, indicating that Compound B decays faster than Compound A.

Conclusion

In conclusion, the decay of Compound A and Compound B can be modeled using the formula for exponential decay. The results show that Compound B decays faster than Compound A, with a decay rate of 18% compared to 12% for Compound A. This analysis has important implications for the storage and handling of radioactive materials, and highlights the importance of understanding the mathematical principles underlying radioactive decay.

Mathematical Formulas

A(t) = A0 * (1 - r)^t (exponential decay formula for Compound A)
B(t) = B0 * (1 - r)^t (exponential decay formula for Compound B)
Ratio = B(t) / A(t) (ratio of the amount of Compound B remaining to the amount of Compound A remaining)
